"Browning the philosopher is read by countless thousands to whom otherwise philosophy would be a sealed book, for exactly the same reason that Macaulay the historian is read by countless thousands to whom otherwise history would be a sealed book; because both Browning's works and Macaulay's works are material additions to the great sum of English literature. Philosophy is a science just as history is a science. There is need in one case as in the other for vivid and powerful presentation of scientific matter in literary form."
